<p> This page describes some of the changes which should be expected
|
||
|
|
in Expat 3. These are intended as notes made by the developers as
|
||
|
|
things get thought through; these can change at any time. This is
|
||
|
|
<em>not</em> a projected feature list for Expat 3; to learn about the
|
||
|
|
target features, please read the <cite><a href="roadmap.html">Expat
|
||
|
|
Development Roadmap</a></cite>. The changes described here are much
|
||
|
|
more focused on the details of Expat 3, and no attempt has been made
|
||
|
|
to balance the description of small changes with major new feature
|
||
|
|
development. </p>
|
||
|
|
|
||
|
|
<p> This list is not complete; we'll add to this as we think of things
|
||
|
|
and have time to write about them. </p>

<ul>
|
||
|
|
<li> All structural event callback functions will return an
|
||
|
|
<code>XML_Status</code> value that the parser will check. This will
|
||
|
|
allow an application to stop or suspend processing without having to
|
||
|
|
use <code>setjmp()</code>/<code>longjmp()</code> hackery. </li>
|
||
|
|
|
||
|
|
<li> The parser will support suspension of parsing to allow an
|
||
|
|
application to pause parsing temporarily. A new
|
||
|
|
<code>XML_Status</code> value, <code>XML_STATUS_SUSPEND</code>, can
|
||
|
|
be returned by the event callbacks to indicate that Expat should
|
||
|
|
suspend parsing; the parser will then return from
|
||
|
|
<code>XML_Parse()</code>, returning <code>XML_STATUS_SUSPEND</code>.
|
||
|
|
Applications can resume parsing by calling
|
||
|
|
<code>XML_ParseResume()</code>. </li>

||
